- Abstract:
- Aiming at the problem of low conductivity of organic phase change material, two-dimensional nu.merical simulation on heat transfer enhancement of phase change of paraffin wax by adding porous media wasconducted with the CFD software. The results showed that both Al foam and graphite foam could improve heattransfer rate effectively,and the efieet of heat transfer of Al foam is superior to that of graphite foam, and theefective thermal conductivity of porosity/ parafin wax composite materials is greater, heat transfer rate is fas.ter ; the solidification time shorten, And the temperature of corresponding points in device is lower after thesame solidfication time with the decrease of porosity.
